913F shaft weight and brezel advice

Hello Titleist, 

After buying my new 913D3 with the Aldila RIP a 70 shaft I am thinking of buying the 913F also. Unfortunatly the Aldila RIP a 80 shaft is not available (in regular flex), what do you think of buying the RIP a 70 with a heavier brezel (which you suggest +0,50 shaft) ?

Thanks in advance for your help!

Kind regards,
Kai 

Kai, you would pro ably benefit more from testing the clubs with the shaft and weight you are thinking of at a retailer with launch monitors. Find a good place where they have trained staff that can help you fit your swing.
